Understanding Blood Relation Puzzles

This question asks us to determine the relationship between two individuals based on a coded expression. We are given specific codes that represent different family relationships. Our task is to decode the given expression step-by-step to find how C is related to Q.

Decoding the Relationship Codes

Let's first understand the meaning of each symbol provided in the question:

Code Meaning
E + F E is the father of F
E – F E is the sister of F
E × F E is the brother of F
E ÷ F E is the son of F

Analyzing the Expression: B – C + Z × G + Q

Now, let's break down the given expression 'B – C + Z × G + Q' into smaller parts and decode each relationship:

  • B – C: According to the rule 'E – F' means 'E is the sister of F', this part means B is the sister of C.
  • C + Z: According to the rule 'E + F' means 'E is the father of F', this part means C is the father of Z.
  • Z × G: According to the rule 'E × F' means 'E is the brother of F', this part means Z is the brother of G.
  • G + Q: According to the rule 'E + F' means 'E is the father of F', this part means G is the father of Q.

Tracing the Relationship between C and Q

We need to find the relationship of C to Q. Let's connect the relationships we've decoded:

  • We know that C is the father of Z (from 'C + Z').
  • We also know that Z is the brother of G (from 'Z × G'). Since Z is the brother of G, and C is the father of Z, it implies that C is also the father of G. So, C is the father of G.
  • Finally, we know that G is the father of Q (from 'G + Q').

Putting these together: C is the father of G, and G is the father of Q. This means C is one generation above G, and G is one generation above Q.

Determining the Final Relation

Since C is the father of G, and G is the father of Q, C is the father's father of Q. This relationship is also known as paternal grandfather.

Therefore, C is the Father’s Father of Q.

Additional Information: Solving Blood Relation Puzzles

Solving blood relation questions involves careful decoding and step-by-step analysis. Here are a few tips:

  • Always decode the expression from left to right.
  • Use symbols or diagrams (like family trees) to represent relationships if it helps visualize.
  • Pay attention to the gender implications of the codes (e.g., 'father' implies male, 'sister' implies female, 'brother' implies male, 'son' implies male).
  • Trace the relationship from the first person mentioned to the second person asked about in the question.
  • Practice with different types of coded relationships.
